描述

Grove – 1線 MAX31850K 熱電偶放大器 1Wire Thermocouple Amplifier

Grove – 1-Wire熱電偶放大器（MAX31850K）是一款熱電偶至數字轉換器，具有14位分辨率和冷端補償。該模塊設計用於與k型熱電偶配合使用。熱電偶的測量範圍比熱敏電阻大得多。例如，我們網站上的這款k型熱電偶的測量範圍為-50℃至+ 600℃。

該模塊基於MAX31850K，集成了放大器，ADC和64位ROM。由於64位ROM，每個器件都有一個獨特的64位串行代碼，允許多個單元在同一條1-Wire總線上運行。因此，使用一個微控制器（主設備）來監控分佈在大面積上的許多熱電偶的溫度是很簡單的。

同樣，這個模塊不能單獨工作，必須使用k型熱電偶，如果你沒有，你可以在我們的集市上考慮熱電偶溫度傳感器K Type-1M。

注意：

通常K型熱電偶的正極為紅色，負極為淺白色，但我們無法保證所有K型熱電偶都是這樣的。因此上圖僅適用於從我們網站購買的K型熱電偶。如果從其他地方獲得K型熱電偶，則需要使用其他方法來判斷正負極。

Grove – 1-Wire Thermocouple Amplifier (MAX31850K)

The Grove – 1-Wire Thermocouple Amplifier (MAX31850K) is a thermocouple-to-digital converters with 14-bit resolution and cold-junction compensation. This module is designed to be used in conjunction with a k-type thermocouple. The thermocouples have a much larger measurement range than thermistors. For example, this k-type thermocouple on our website has a measurement range of -50℃ to +600℃.

This module is based on the MAX31850K, which integrates amplifier, ADC and 64-bit ROM. Thanks to the 64-bit ROM, each device has a unique 64-bit serial code, which allows multiple units to function on the same 1-Wire bus. Therefore, it is simple to use one microcontroller (the master device) to monitor temperature from many thermocouples distributed over a large area.

Again, this module can’t work alone, it must work with a k-type thermocouple, if you do not have one, you can consider Thermocouple Temperature Sensor K Type-1M in our bazaar.

Attention:

Usually the positive pole of the K-type thermocouple is red and the negative is light white, but we can’t guarantee that all K-type thermocouples are like this. So the above diagram is only for the K-type thermocouple purchased from our website. If your K-type thermocouple is obtained from other places, you need to use other methods to judge the positive and negative.
